Application filed September 2S, 1906. Serial No. 336,561.

To all whom it may concern: ""Beit known that I, JAMEs HOPKIRK, e citizenllof Ythe United States, residing at Seattle, inthe county of King and State of Washington, have invented new and useful Improve ments in Conveyor-Pipes, of which the following is a specification. The invention relates to conveyor pipes and more particularly to pipes which are 3o used for conveying earth andimilor mete lrials by means of a flow of water.

Objects ol the invention ore to provide a Spipe of .great efficiency and comparatively low cost of manufacture :ind maintenance. .i3 Further objects of the invention are to provide o. combined surface within the con veyer pipe which will present gres/.t weareresisting qualities where necessary and at the f same time also provide a high conveying cazo pacity; which will possess greet durability and at the same time oder little frictional resistance to the flow of materials and iluids through the pipe; to provide for holding the weer blocks .securely in position and yet permitoftheir being readily removed when de sired end to 'provide at the same time for protesting the blocks except upon the surfaces which it is desired to expose for wear.

These and other objects of invention Will so in part be obvious and will in part more fully appear from the speciiication.

The invention consists in the novel parts, articles, improvements, arrangements and combinations herein shown and described.

.c5 The accompanying drawings, referred to herein and forming .a port hereof, illustrate one embodiment of the invention, the'serne serving in connection with the description herein to explainthe principles of the invenfo tion.

Of the drawings: Figure 1 is e. vertical sectional view .of a pipe constructed in aclcordance with the principles of the ,invention; Fig-2 is elfragrnentary transverse sec- 4.3 tion neer the central horizontal exis of the pipe looking downward; lend Fig. 3` is a. vertical section of a modified forni. y

Referring to the accompanying drew-ings which illustrate by way ofoxanrpleaconveyer 5o pipe embodying the principlesof ,the inventtion, a cesing which will ,usuell-y be cylinr drical in forni, .issliown and indicated by the reference numeral l. These-id eesing may be composed -ot vnr-ions meteriels, il` desired, `but iron or steel will be 4found 'suitable for various reasons. .such osnoolnporetively low Specicetion of Lettere Potent.

cost, ease of menufecture, and greet strength and durability for amount ol" material in volved. rArranged within. the seid casing l so as to cover the lower4 Aportion. of the inte' riorsurfsce thereof, is shown nreniovable' floor-ol wood or other weer resisting mete rial, for taking up the weer due to the attrition caused by theparticlcs of' solid metter carried along in the stream of water passing; o5 through the coi'iveye pipe. As shown here in, the said door coiixsists of n. series of blocks 2 of Wood ol i1-cnet and onient'el lor-rn. fto for as wmcerns rtain ie tures of 'the inve tion, however, floor may be of soin, 'i'f other forni. The ray :2l-f ranged so that the groin substantiellj radielly arranged, that is, the end oi the grain is presented as a Wearing' surface tothe passing materiel, it being well known that wood placed with the groin so arranged provides e superior w .ering surface. Suitable ineens ore provided for holding the blocks .securely in position, seid ineens at thee/:une time pernntting their ready re moval when it desired to renew the blocks after lche old ones ore so worn. ns to he no longer suitable for use. lt is also desirable to protect the ends of the blocl troni the es tion "of the solid materials pas... ng; through 8F. the I ipe, as otherwise the ends of the blocks Wou d be subjected to great weer :rnd the finer particles of materials would ,gradually work underneath tho blocks and tend to dislodge or lift them ziwny from the cosiner 1, to a greater or less degree. Means for glowinplisliing these ends ere provided in the prosent invention and are shown herein in the form of continuous strips 3 errenged longi-V tudinally of the pipo cosine' on its intr-:rior 9 The said strips nre shown oi angled forni, one pertextending outwerdly so :1s to -orin a ilange i Ywhich takes over the ends o'r' the wooden blocks constituting .the .door or lining of the pipes, the other portion ol the said strips 3 being; curved `so to iit snugly the 'interior fac-ing of the pipe. The seid curved portion oi' rthe strips is ntteoheil to the interior surinceof the rinsing l in any suitable nmnnor, es for instance .by e double row of rivets 5, es shown in the drawings.

4The curved portion of the strips may be proportioned so as to continue up inside the coslng 4ebove the central horizontal exis of the pipe. By such en arrange; ,all the weer is teken up by tlfte wooden`v s 2 the motel strips bent again so as to resent a smooth, vertical edge 7 to the bloc '2, such edge serving to present a surface past which the blocks may be readily slid during their insertion and removal and which will also hold them accurately to position in the pipe.

Great advz'intagesy are secured by means of the use of themetal casing and 'the interior Hoor of wooden blocks to which the inventlon 1n certain of its features is directed.

leaky by alternate wettings and dryings, and while offerlng less fru-tionm the first 1nstanco than Vwooden surfaces they also gradually take on a polish which still further decreases the friction. 'lhis gives a material increase in the conveying capacity of the pipe for a given cross-se .tional area ol" pi ne and a given flow or ressure of water. The wooden blocks on tie other hand serve to take up substantially all the wear and being renewable provide with the casing a pipe which is of very high efficiency and approXimately unlimited durability. lt will be further noted that the metal casing or pipe proper is protected on its interior by either the wooden blocks or the metal strips to a point just above the horizontal axis of the pipe so that substantially the entire Wear is ta ien up u on the said auxiliary surfaces.

From al the foregoing it will be understood that a. conveyor pipe ,has been provided which realizes the objects of invention and the advantages hereinbefore set forth,

' together with other obje-cts and advantages.

(ifi

The invention, in its broader aspects, is not limited to the particular construction shown, nor to any particular constructions by which it has .been or may be carried into etl'ect, as many changes may be made inthe constructionv without departing from the main principles of the invention and Without sacrificing its chief advantages. i
